Components that do not meet conventional standards, have complex and unique shapes. These irregular parts require unconventional processing methods in the production process, such as CNC machining, forging, die-casting, etc., and even in some cases, manual manufacturing and fine polishing are required. Their size and outer contour are complex and varied, making it impossible to produce them on a large scale through standardized production lines. This also determines the long manufacturing cycle and high cost of non-standard shaped parts
